CAN Bus Message Recording and Wireless Data Transmission Equipment User Manual
In the acceptance code, a position 1 indicates that a frame whose corresponding
bit is 1 is received; a position 0 indicates that a frame whose corresponding bit is
0 is received.
In the mask code, the corresponding bit determines whether the corresponding
bit of the received code is valid. When a certain bit is set to 1, the matching
function of the corresponding bit of the acceptance code is enabled. Receive if
the bit in the received data frame matches the bit in the acceptance code. If a
certain bit is set to 0, this bit does not participate in matching and all are received.
There is a one-to-one correspondence between the acceptance code and the
mask code.
Each CAN channel supports the setting of eight groups of acceptance codes and
mask codes.

Filter calculator
For user convenience, the configuration tool comes with a filter calculator. The
required acceptance code and mask code can be generated by specifying the frame ID or
specific bits in the ID based on the user's needs. Figure 4.14 shows the filter calculator.
The filter calculator provides several common filter modes, which helps users quickly
set filter rules. If the several modes provided in the filter calculator cannot meet the user's
needs, the user can select the "Custom filter settings" checkbox. The appropriate
acceptance code and mask code are generated based on the bit definition information of
the acceptance code and the mask code.
